DISK ATTACHMENT FOR PLOWS.

To all whom it may concern:

Be it known'that I, RICHARD J. KULIsoH, a citizen of the United States, residing at Adams, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Disk Attachments for Pleas, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to agricultural devices, and particularly to harrow attachments for plows.

The primary object of my invention is the provision of a very simple attachment adapted to be applied to the beam of an ordinary plow and adapted to support a plurality of disks.

A. further object of my invention is to so mount the disks that they maybe disposed in adjusted relation and at various angles to the beam.

Still another object is to so construct the attachment that itmay be readily taken apart for the removal or replacement of the disks.

Still a further object is to provide improved means for rotatably supporting'the disks.

Other objects will appear in the course of the following description.

My invention is illustratedin the accompanying drawings, wherein:

igure 1 is a side elevation of my harrow attachment applied to a plow beam; Fig. 2 is tion, the plow beam being also 1n section; Fig. 3 is a side elevation of one of the harrow disks showing its attachment to the hub; Fig. 4. is a section on the line 4-4l of Fig. 1; and Fig. is a side elevation of one of the hub sections detached.

Referring to these drawings, 2 designates the beam of a plow of any suitable character or the beam of a cultivator. Disposed against one face of the beam is a beam clamping plate which is designated 3. This plate is provided with openings for the pas sage of clamping bolts 4, and 5 is the plate on the side of the beam opposite the plate 3 through which the bolts 4 pass. The plate 3 has oppositely disposed bearings for the reception of the upper end of a crank arm 6, and passing through the plate 3 at a plurality of points are set screws 7 which, when set up, bear against the vertically portion of the crank arm 6 and hold the Specification of Letters Patent. 7

crank arm in an adjusted position within the clamping plate. The middle of the crank arm 1s outwardly bent and then downwardly extended and is provided with spaced collars 8 and 9, each of these collars being formed with set screws whereby they may be adjusted upon the depending portion of the crank arm.

Disposed on. each, side of the depending portion of the crank arm are the downwardly and rearwardly extending wheel supporting members or standards 10. As shown, there are two of these standards and the upper end of each standard is inwardly bent and then formed with a semicylindrical seat 11. The upper ends of the standards and the seats receive the depending portion of the arm 6. Clamping bolts 12 and 13 pass through the ends of the standards on each side of the seats and clamp the standards securely in place. These clamping bolts may be set up tightly enough so as to prevent an r rotation of the standards upon the depending portion of the arm 6 or they may be relatively loose and allow of rotary movement of the standards upon the arm. The collars 8 and 9, previously re ferred to, are for the purpose of preventing vertical movement of the standards with relat-ion to the depending portion of the crank arm, and by means of these collars the standards may be adjusted vertically.

The standards extend downward and rearward and each terminates in a head 14, each head having a central passage with flared ends. The hub upon which the cultivator disks are mounted, as illustrated, is formed in four sections. tions is designated 15. The middle disk 16 is clamped between two of these sections, while the end disks 17 are each clamped against the outer face of one of the sections. Each section comprises a disk-like portion 18'having a conical hub 19 projecting from the inner face, the hub terminating in. a cylindrical portion 20. At its edge the disk like portion 18 is provided with a relatively thin extension 21 perforated for the passage of bolts or rivets. To support the middle disk 16, two of these sections are disposed one on each side of the disk and confronting each other and bolted to each other by bolts or rivets 22 which pass through the relatively thin marginal portions of the disks 21. Each of the disks 17 is disposed against the fiat face of the corresponding section 16 and Each of these sec-- n themselves may y from its hub section by loosening -the bolts k and are "designed to for 12 inch plows,

It will be seen that as the hub of. each disk is conical wear may be taken up from time to time by tightening up upon the bolt 23. is formed with an oil hole 24: which extends down into the bearing formed on the head and extends upward to the exterior of the head and terminates in an oil cup'2'5.

It will be seen that by removing the collars 8 and 9 the standards may be readily released from 't lrefcrank arm 6, and that by removing the bolts12 and 13 the standards may be separated from-each other, and if-the bolt 23 is likewise removed the separation of "standards will permit a separation of the several, hub sections of the several disks. This permits 'the "ready removal oi? the disks for grinding'or substitution and permits the ready replacement of the disks. The "disks be readily removed each 22. It will be obvious that the angle of the disks to the plow beam may "be readily adjusted by adjusting the crank arm 6 and that the disks may be raised or lowered to any desired position and held in their adjusted relation. It m'aybe'said that in actual use the disks are twelve inches in diameter 4% inches for 14 inch plows, and 5 -inches apart for 16 inch plows. Instead of using bolts 22 1 may rivet the disks to the hub sections.

This attachment may be used on walking plows, gang plows, ortractor driven plows,

and is of particular advantage inasmuch as theground is immediately harrowed or sliced 1 by the disks, thus eliminating the necessity sitely disposed standards, said standards converging at their upper ends and being formed each with a seat partially embracing the supporting member, means for clamping the standards'to the supporting member, the outer ends of the standards being formed with enlarged heads, each head having a transverse opening flared at its ends, a harrow disk disposed having oppositely disposed hub sections attached to its opposite faces, each hub section having a "disk-like portion, central conical portion and a cylindrical extension, and a harrow disk di'sposedexterior to each standard and each formed upon its inside face with a hub comprising a disk like portion and a central conical portion with a cylindrical extension, said conical portions and cylindrical extensions o'f'the several hub sections being disposed within the openings in the "headsya nd abolt passing through all of the hub sections and binding the disks in place upon the standards.
